. T0 aZZ whom it may concern.-

Be it known that I, JOHN A. HUTOHINSON, a citizen of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Horseshoe- Na-il- Finishing Machines, which are fully set forth in the following specification, reference being had to the accompanying drawings, in which Figure 1 represents a side elevation of the upper or working portion of a machine embodying my improvements; Fig. 2, a plan view of the same; Fig. 3, a vertical section of the same, taken on the line 00 00, Fig. 2; Fig. 4., across-section of the same, taken on the broken line y 3 Fig. 3, and looking. toward the front of the machine; Fig. 5, a vertical section of the same, taken on the line 2 2, Fig. 2, and looking toward the rear of the machine; Fig. 6, a detail plan section taken on the line a a, Fig. 3; Fig. -7, end and side elevations of the nail rolls and box detached from the machine; Fig. 8, a detail elevation of the feedregulating device; Fig. 9, a detail section of a portion of the die-wheel; Fig. 10, a detail My invention relates to machines for coldfinishing horseshoe-nails, the machine being intended to operate upon blanks previously formed, either by forging or punching. The machine is intended to finish these blanks, so as to produce completed nails, ready for driving, by rolling, beveling, and trimming the blanks on one and the same machine. I am aware that this result in the finishing of horse shoe-nails has been obtained heretofore; but, so far as known to me,these finishing-machines have been provided heretofore with an inter-. mittently-moving feed-carrier, by which the blanks are brought successively to the action of rolling, beveling, and trimming devices, this carrier being stopped while these several devices act upon the blanks. In my present invention I make a radical departure from this Serial No. 207,144. (No model.) v

enable me to fully carry out the main idea of my invention.

I will proceed to describe in detail the construction and operation of a machine in which I have practically embodied the invention in one way, and will then point out definitely in the claims the particular improvements which I believe to be new, and wish to protect by Letters Patent.

In the drawings, A represents the main or supporting frame of the machine,which is here shown mounted on suitable supporting-legs, a, so as to elevate the working parts of the machine, which are mounted on the main frame a' convenient distance above the floor.

Near the front end of the machine is a large die-wheel, B, which is secured to ashaft, 1), arranged transversely of the frame and mounted in suitable bearings thereon. This die-wheel is constructed so as to provide aseries of rollerdies upon its-periphery, which act in conjunction with suitablerollers to cold-roll the blanks upon one side. The web b of the wheel is solid, having an enlargement at the center, which constitutes the hub, by means of which it is secured to the shaft.- At the periphery the web-isalso enlarged or thickened, so as to provide a thick heavy rim, b which mostly projects at one side of the web, as shown in Fig. 4 of the drawings. In the outer face of this rim rectangular recesses are cut for the reception of the roller dies. plate, 0, is bolted to the face of the rim portion of the die-wheel, and is provided with a flange, c, which extends inward underneath the projecting portion of the rim, as seen in Fig. at of the drawings. The annulus is also An annular provided at the outer edge with a similar flange, c, which extends in the otherdirection, or outward from the body, and is provided upon its periphery with gear -teeth, as shown in Figs. 2 and 4 of the drawings. It will beseen from this description that the plate 0 covers the recesses in the rim of the wheel on the outside of the latter, and also closes them at the inner end or bottom, leaving them open at the periphery of the wheel only. Pockets are thus formed around the wheel, in which the roller-dies D are set. These dies are composed of two cheek-pieces, (Z, set on each side of the pocket, and a center piece, (1, which isa little shorter than the others. The inner ends of the die-pieces are concave, so as to rest upon the flange c of the plate 0, while the outer ends are conveX,to correspond with the wheel. Set-screws d are placed in the flange a, one behind each of the die-plates, whereby thelatter may be adjusted accurately in position. The cheek-pieces are intended to be brought flush with the periphery of the wheel, and the center pieces are sunk sufficiently to form a dieopening about the size of a nail, this opening being tapered in both directions, as rollerdies usually are. Notches b are sunk in the periphery of the wheel in front of the dies, and are adapted to receive the lugs or projections on the carrier, which will be described presently, and are large enough to accommodate the heads of the blanks. These depressions are distant from each other a little more than the length of large-sized nail-blanks, and the size of the roller-dies is such as to accommodate blanks of the largest size which it is desired to finish on the machine.

The endless carrier E for the blanks or nails is arranged to run around the die-wheel. This carrier, as shown in the drawings, is composed of two thin strips, 6, of steel or othersuitable metal, separated from each other slightly and joined by lugs or projections 6; also of metal, and riveted or otherwise securely fastened to the respective strips,on the under side thereof, as shown in Figs. 1 and 2 of the drawings. These lugs are arranged at the same distance from each other as the recessed notches b in the periphery of the die-wheel, and are adapted to enter them, thereby providing means for driving the carrier.

In the upper faces of the lugs notches e are out, which are adapted to receive the heads of the nail-blanks, and when the heads of the blanks are placed in these notches it is evident that the forward movement of the carrier will pull'or drag forward the blanks, as the heads cannot slip back through the notches. The blank-carrier is also run around an idle-wheel, F, mounted at the rear end of the frame and provided with notches f in its periphery, adapted to receive the lugs on the carrier. The boxes f, in which the journals of this wheel are mounted, are made adjustable on the frame, being secured to the latter by means of bolts f passing through slots f 3 in the bearings, and behind each is arranged a set-screw,

f, whereby this idlewheel may be adjusted for the purpose of keeping the carrier perfectly taut.

The main driving-shaft G of the machine is provided with a pinion, g, which engages with a large gear-wheel, G, mounted (.n a countershaft, which also carries asmall pinion, g, and the latter engages with a large gearwvheel, 'G, on the shaft of the die-wheel, thereby driving the latter, and with it the carrier, as described above. The rotation of the die-wheel is forward, so that the carrier is taken up over the wheel and moved to the rear ofthe machine in the direction shown by the arrows in Fig. 3 of the drawings. It is evident that if nailblanks are placed in the carrier by putting their heads in the notches of the lugs they will be carried upward over the wheel, dropping into the roller-dies as they are moved along. It is during this movement of the blanks with the die-wheel that they are rolled. This I accomplish by means of a roller, H, which is suitably mounted to run in contact, or nearly so, with the diewheel,' so that the blanks will be drawn head first between it and the wheel, and as they are drawn under the roller will be rolled down in the roller-dies by the wellknown action of these devices as they have been heretofore used. I have shown in the drawings a particular way of mounting this roll, which will now be described.

The roll is mounted in a box, 71, the central portion of which is cut away, as shown in Fig. 7 of the drawings, and in the ends of which are holes for the receptionof the journal-pins h of the roll. It is desirable to use a pair of rolls for this purpose, one running in contact with the other; hence I mount a second roll, H, above the former in the same box and in the same manner. A casing, I, of circular form, is secured fi rmly to portions of the main frame in front of and extending upward over the diewheel. This casing is provided with a socket, 1', adapted to receive the roller-box, which is set therein and fastened in place by means of a cap-piece, i, fastened to the case by screwbolts. A set-screw, i, is inserted in the cappiece, which works against the roller box for the purpose of setting up the latter into proper working position. If the nail blanks are worked down sufficiently to enable the proper reduction thereof to be effected by one operation of the rolling devices, only one set of rolls is necessary, and obviously each blank will be rolled down as it is drawn under the rolls by the die-wheel. Sometimes, however, blanks are used which are only roughly formed, and a very considerable reduction is required by the finishing-rolls. In. such cases it is desirable to use more than one set of rolls, which are adjusted so that the first will do only a part of the work, while the second set is adjusted to effect a still further reduction of the blanks, and so on, if more than two are required. In the drawings an arrangement of rollers is shown for this purpose. Three sets of rolls are shown, the casing being enlarged rier and on the die-wheel in various ways-in fact, it maybe possible to feed the carrier by hand. An automatic device for this purpose is preferable, however, and I have shown one in the drawings, which will now be described.

A worm-screw, J is mounted horizontallyin suitable bearings on the main frame close to the periphery of the die-wheehbut eXtending out to one side of the latter. The spiral groovej of the worm terminates at one end in a cam-groove, j, running directly around the shaft, the cut of this groove being almost entirely on one side, leaving the body entire on the other side, as shown in 'Figs. 3 and 10 of the drawings, thereby making a kind of cam projection, 9' on one side of the worm. This cam projection is flush with the main circumference of the worm, and for certainty of action is serrated upon its periphery, as seen in Fig. 10 of the drawings. The worm is arranged so that this cam at one end will be directly opposite the depressions in the roller-dies as the diewheel is rotated. A guide-bar, J, is arranged back of the worm and nearly in contact with its periphery, which acts in connection with the worm in the well-known Way in screw-feedsofthisdescription. Itextendsfrom one end to the other of the spiral of the worm, but terminates at the cam-opposite the diewheel. The shaft of the worm is extended beyond the cam, and is provided with a pinion, j, which is engaged by the geared flange c of the annular plate 0, thereby providing for the required rotation of the worm. The blanks areplaced by the attendant in the spiral groove of the worm, at the outer end thereof, just in front ofthe guide-bar, and by the rotation of the worm will be carried along inward to the die-wheel. WVhenthe blank reachesthe inner end of the spiral, it will be'delivered into the straight groove of the cam as the latter comes round in front of the die-wheel, Whereit will at once come under the action of the cam projection 9' by which it will be pressed inward and delivered to the blank-carrier, thehead being seated in the notch of one of the lugs in the latter-and the body resting in the depression of the die immediately in front of this lug. This operation is illustrated in Fig. 10 of the drawings, and it will be understood, of'course,

- that the worm and die-wheel are so timed in the end of the worm, being pivoted to a suitable support. The inner end of this lever is bent upward, so as to enter just between the die-wheel and the worm. the-lever extends straight outward and is provided with an adjusting-screw, is, by means of which the normal position of the clamp may be regulated. A spring, k, is arranged to act upon the inner or bent end of the clamp, so as to force it outward or toward the worm. The adjusting-screw is arranged so that it will strike the seat below it as the clamp is turned upon its pivot under the influence of this spring, when the inner end is brought up to the outer periphery of the worm, or to a point where it will nearly or quite come in contact with the cam on the worm.

Now, obviously, when the straight groove of the worm is opposite to the inner end of the clamp, there is an open space in front of the inner end of the latter, so that the blank is readily delivered intothe groove, and just in front of the clamp. Now, as the cam on the worm is brought around to the clamp by its rotation the blank will of necessity be pinched between it and the clamp, the latter yieldingbackward on its pivot and the blank being held between the two .by the force of the spring. The spring is light, however, the object being simply to steady the blank and The other end of.

hold it in proper position for delivery, while at the same time it is moved upward until the carrier is continuous it is also necessary that the pointing mechanism shall be movable. I will now proceed to describe these parts of the machine? Near the middle of the machine, and on the same side as the die-wheel, is an upright support, I1,'which, as shown in the drawings, surrounds the main driving-shaft, extending on each side and above and below the latter. This support is rigidly fastened to suitable parts of the main frame, so' that it is practically a part of the latter. It is substantially rectangular, and its upper and lower edges have bevel faces Z, as shown in Fig. 5 of the drawings. A strong heavy plate or casting, M, l

is constructed with beveled orinclined gibs m on its back face, which are adapted to receive the bevel edges of the support L, so that the plate is thereby secured to the support, and at the same time may be moved in a horizontal direction thereon as'a suitable guide or way,

thejoint between the two being a kind of dove ICC tail, as shown in Fig. 5 of'the drawings. On

the front or outer face of this same plate are upright or vertical gibs m m, the first of which is stationary, while the second is movable, being secured to the plate by screw-bolts passing through slots in the gib, as shown in Fig. 6 of the drawings. A second sliding sup port or plate, N, of substantially rectangular form, is constructed with bevel edges n at its sides, whereby it is adapted to be fitted and held between the upright gibs, just mentioned, on the front side of the plate M.

The gib m is made movable,in order to permit the insertion of the plate M between the two from the side when this latter gib is moved outward to its fullest extent. The gib is then set up into place against the plate N, as shown in Fig. 6 of the drawings, by means of setscrews 111.,arrarged in lugs back of the gib. It will be seen then that the plate N, while it is secured to the plate M, is also movable ver tically thereon. There is, therefore, provided a kind of compound or double slide, by means of which both a horizontal and vertical move ment may be given to the sliding plate N. The first plate, M,ismovable only in a horizontal direction, and may be termed the horizontal slide; but the second plate, N, is carried hori zontally by the movement of this horizontal slide, and at the same time is movable vertically on the latter, and may be termed the vertical slide. These parts are constructed and arranged so that the vertical slide will stand in about the same plane as the die-wheel; and the upper portion of the horizontal slide, as shown in the drawings, is curved or rounded and projects slightly over the vertical slide, as seen, in Fig. 5. A long die-block, O, is bolted to the front face of this upper portion of the slide M, so that it will hangjustabove thetop of the vertical slide N. In this block are mounted, first, at the end nearest the die wheel a beveling-punch, 0, then, near the mid dle, a shearing-punch, 0, and then, near the other end, a second beveling-punch, 0 though the latter may or may not be used, as desired. These punches are all secured in the block in any usual way, and hence have no vertical motion, but will have a horizontal movement with the horizontal slide whenever motion is communicated to the latter. These punches are arranged at about the same distance apart as the distance between the lugs on the carrier, or the length of an ordinary nail, measuring from the front edge of one to the corresponding edge of the next. The dies corresponding to these punches aremounted in the upper end of the vertical slide N-first, toward the die wheel is a beveling-die, n, then a shearing or trimming die, n, and,lastly, a second bevelingdie, if. These dies are of ordinary construction, the beveling-dies being simple punches with beveled ends. The shearing-die shown in the drawings is a three-part die, in which the side pieces or cheeks are separate. This die is old and well known in the art and need not be particularly described here. The particular construction of the die isnot, however, a matter of consequence. Any die that is adapted to do the work will answer.

The dies are mounted in the vertical slideby recessing the upper portion of the latter and fastening thereto a block, N, recessed, as shown in Figs. 3 and 6 of the drawings, the recesses in the two parts, when brought together, forming the proper seats for the several dies; The vertical slide is also cut out underneath the respective dies, as shown at n in Fig. 3 of the drawings, to provide for the insertion of set-screws n underneath the two bevelingdies and the separate pieces of the shearing-die. Settingscrews n" are also inserted in the face-block N, which work against the sides of the dies. Vertical set-screws 0, and similar horizontal screws, 0", are also applied to the punches in the block 0. The two slides are arranged so that the nail-blank carrier running along from the top of the die-wheeltoward the rear of the. machine will pass directly between the die-punches and dies. The blanks will therefore be carried in a horizontal position in between the dies and die-punches; and in order to provide for the proper transfer of the blanks from the die-wheel to the beveling and shearing devices a horizontal guard, E, is mounted on a suitable support, and extends just, underneath the carrier from the die-wheel to the slides As the blanks leave the die-wheel and are carried off in a nearly horizontal direction by the carrier their points will drop down between the two strips of the carrier, and this would of course tend to displace the blanks. The guard just described prevents this result, as the points rest upon it, and so are held up during the. travel of the blank over this space. Now, it is obvious that when the blanks are brought into proper position over the respective dies, if they should be stopped and then the vertical slide be moved upward, the blanks would be beveled and sheared in the ordinary way; but the blanks are not stopped the motion ol'thecarrier being continuous, as already stated. It is obvious, then, that ifas the blanks are brought into position over the dies a forward motion is given to the horizontal slide corresponding to the movement of the carrier, so that the two will travel together, and at the same time an upward movementis given to the vertical slide, the operations of beveling and shearing will be performed upon the blanks in the same way as though stationary. It will be seen at once that these motions of the two slides are necessary to the practical operation of the machine, and I will proceed to describe the means by which they are produced.

As already stated, the main shaft passes through the support L. In fact, it is journaled in this support, as shown in Fig. 5 of the drawings. This end of the main shaft is shown somewhat enlarged, and on the outer end thereof is an eccentric or cranlepin, P, which extends outward from the support L through openings pin the respective slides. The opening 12 in the vertical slide is circular, and has inserted therein a brass box or bushing, Q, which extends inward through the ICO 25 on the carrier.

5 the vertical one.

opening 19 in the horizontal slide and receives the crank-pin. The opening 1) is adapted to receive the projecting portion of the box or bushing Q, being fitted to the latter in a hori- 5-zontal direction, but elongated in a vertical direction in order to accommodate the vertical movement of the pin in its rotation. The box Q is preferably surrounded with a sleeve, g, to take the wear occasioned by the movement of the box in the horizontal slide. Now,

it is obvious that the rotation of the main 7 shaft, carrying with it the crank-pin, will impart both avertical and horizontal movement to the vertical slide, and the horizontal movement of this slide will also be communicated to the horizontal slide through the box Q. In other words, the crank-pin will impart a horizontal movement to the horizontal slide and a vertical movement to the vertical slide. The

crank-pin or eccentric must be regulated with reference to the movement of the carrier, so that it will impart a corresponding horizontal movement to the slides, Its orbit is equal to the distance between the centers of the lugs It will be seen from the rela- 7 tion of the parts that when the crank-pin is at its limit in the direction of the die-wheelthe slides will be at the limit-of their horizontal movement in the same direction, and the vertical slide will be at the middle point of its movement upward. The forward movement of the crank-pin will now move the slides for: ward with the carrier, and at the same time 'will move the vertical slide upward, the limit 3 5 of this motion being reached when the crankpin is half-way over and the slides are at the middle point of their travel rearward. It is about at this point that the dies are brought into operative position, so that the beveling 0 and shearing will be completed at the finish of the upward movement of the slide. The movement forward of the'crank-pin from this point will'obviously carry the slide still farther to the rear, and at the same time depress WVhen the crank-pin is clear over, the horizontal movement ends, and as it then turns on its backwardpath the reverse operation'will obviously be effected, the slides being carried back to their startingpoint, the vertical one being depressed to its limit at the middle point of travel and raised on the last quarter. Now, during these movements of the slides, if a blank is in position in the carrier at one of the dies, it. will be beveled or trimmed, as the case may be, and if the carrier is full, so as to bring a blank to each of the dies, they will all operate at the same time to bevel or trim these blanks in position. The return or backward movement of the slides is about equal to the length of a nail, so that the blanks will be caught successively between the beveling and shearing dies mounted on the slides, as described, and the operation of beveling and trimming them will be effected in succession'upon each one, but

while they are in continuous motion.

A guard, E similar to the guard E, is arranged just below the carrier in rear of the slides. This guard supports the points of the finished'nails as they are carried away from the slides by the movement of the carrier, and fills the space between the slides and the idle-wheel. Obviously the finished nails will 'be carried forward to the idle-wheel and down fastening a flange or collar, R, to the shaft and securing the pinion to this collar by any suitable means. In the drawings this flange'is shown provided with circular slots'r, through which screw-bolts r pass, that enter a flange, 9 on the pinion, thereby securing the latter to the shaft. Now, whenever it is desired to adjust the machine for different nails, these fastening-bolts are loosened from the pinion,

when the latter may be slipped along on the shaft and disengaged from the wheel G. The main shaft isthen turned backward or forward, as the case may require, thereby changing the relation of the crank-pin to the slides;

but at the same time it is evident that the diewheel, and so the blank carrier, will remain stationary; and when the pinion is slipped back and secured to the main shaft again and the machine started up it is evident that the relation between thecarrierand the slides will be found to have been changed.- The circular slots in the flange R permit this adjustment between the main shaft and its pinion.

If the machine is to be adjusted for nails of a larger size than it has been finishing, the shaft or crank-pin should be turned backward in making this adjustment, but if for those of a smaller size it should be turned forward; and the different parts may'be so constructed relatively that the change of about one tooth between the pinion and the next gear-wheel will effect the adjustment required to pass from one size of nail to another.

It will be seen from this description that the IIO present machine differs radically from finishing-machines heretofore used. The movement or travel of the blanks is continuousfrom the time they are received by the machine until they are discharged therefrom. The rolling of the-blanks is accomplished by drawing the nails underneath the roller,instead of moving the latter, the roller-die being movable and carrying the blank along with it. The pointing mechanismsthat is, the devices for beveling and trimming-are movable to correspend with the travel of the carrier, and are operated to perform their proper functions while traveling; and these devices are all ar-' ranged in a vertical plane instead of a horizontalone, as has been the general rule heretofore; and the blanks are carried forward in a vertical plane instead of one that is horizontal. These are prominent features which distinguish this invention from other finishingmachines. I do not wish to be understood, however, as limiting my invention to the machine organized precisely as herein shown and described. A great many changes may be made without losing the main and controlling characteristics of this invention. It is possible to construct the devices so that they may be arranged to operate in a horizontal plane, suitable guideways being provided to keep theblanks in proper position. In the drawings the machine is shown with the carrier traveling from front to rear in nearly a horizontal position. This particular arrangement may be changed; and, in fact, I have found that in some respects better results are ob tained by elevating the rear of the machine above the front, sothat the travel of the blanks will be up an incline.

The particular devices which are herein shown and described may be modified in construction, or may be replaced by others for accomplishing the same result, without departing from the leading characteristics of the invention; and I do not wish to be understood as limiting myself to these particular devices for accomplishing the rolling and the pointing of the blanks, so far as the main features of the invention are concerned, which I wish to be understood as claiming broadly. I believe I am the first to finish horseshoe-nail blanks by rolling, beveling, and trimming them while in a carrier that is continuously moving; and I believe that I am the first to provide a pointing mechanism that travels with the carrier for the purpose of pointing the blanks while they are in motion; and I believe I am the first to provide movable roller-dies and a carrier which receives theblanks, and in which they are carried forward under a stationary roll, and I wish to be understood as claiming, broadly, these improvements in horse'nail-finishing machines.

The utility of the invention is obvious. In the machines having an intermittent carrier and devices adapted to finish the blanks only when at rest nearly or quite as much time is consumed by the periods of rest as by those of motion. "With my invention there are no periods of rest, and the carrier can be moved just as rapidly as when it is in motion in the former machines. It is evident, therefore, that the capacity of the machine is nearly, if not quite, doubled, so that it is capable of finishing nearly twice as many nails in the same length of time as the old machine, and without any material increase in power.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is
